(46) Reduce all outputs to minimum.
a. Performance Check
(1) Press corresponding pushbutton for indications as listed in (a) through (c) below:
(a) TRIGGER MODE to NORM.
(b) CH 1 and CH 2 input coupling to 1 M: DC.
(c) 'V to off (cursors off).
(2) Position controls as listed in (a) through (c) below:
(a) CH 1 VOLTS/DIV switch to 5 mV.
(b) CH 1 and CH 2 VOLTS/DIV VAR controls cw to detent.
(c) TRIGGER LEVEL control to midrange.
(3) Set oscilloscope calibrator for a CHAN 1, VOLTAGE mode output of 20 mV at 1
kHz.
NOTE
Combine steps (4) and (5) below to avoid resetting standards.
(4) Adjust TRIGGER LEVEL control for most positive voltage that produces a
barely triggered display when selecting + and - SLOPE. If A TRIGGER LEVEL readout
indication is not within limits specified in + peak column in first row of table 10, perform
b below.
(5) Adjust TRIGGER LEVEL control for most negative voltage that produces a
barely triggered display when selecting + and - SLOPE. If A TRIGGER LEVEL readout
indication is not within limits specified in - peak column in first row of table 10, perform
b below.
